Smallest Formula 1 Car model in the world

The length of the model car is the smallest in the world is only 0285 mm, more or less the equivalent of a grain of sand.In order to achieve such a model of formula 1 car it took less than 4 minutes.. It was made ​​up of 100 microscopic layers, each consisting of 200 lines as microscopic.

The process, already well known in the scientific community, called "two-photon lithography." It is a laser beam focused on a liquid resin to make it solid, leaving behind a line of solid polymer great few nanometers. Compared to printing techniques 3d "traditional", the laser can create solid material throughout the liquid material instead of working by adding layer upon layer

It was created by Vienna University of Technology's equipment, in Austria.
